YARN-DYEING MACHINE.

SPECIFICATION forming part of Letters Patent No. 415,888, dated November 26, 1889.

Application filed March 2'7, 1889. Serial No. 304,985. (No model.)

To all whom it may concern-.-

Be it known that I, LEONARD \VELDON, of Cohoes, in the county of Albany and State of New York, have invented new and useful Improvements in Yarn-Dyeing Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to machines for dyeing yarn in skeins.

The object of this invention is to provide a machine which shall have the capacity of carrying a large quantity of yarn in the process of dyeing and occupy a minimum space; and to that end the invention consists, mainly, of a machine comprising a dye-liquor vat, vertical rotary disks above said vat, endless bands or chains extending around the top portion of said disks and suspended therefrom and passing through the interior of the vat, and yarn-supporting bars carried on said bands or chains at the inner and outer sides of the latter, all as hereinafter more fully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a front elevation of a yarn-dyeing machine embodying my improvements. Fig. 2 is a vertical transverse section on line as in, Fig. 1. Fig. 3 is an enlarged detached plan view of one of the yarn-supporting frames, and Fig. 4. is an end view of the same.

Similar letters of reference indicate corresponding parts. i

A represents the vat containing the dye liquor.

B and B denote two pairs of disks secured to the ends of the shafts a a, which are disposed axially horizontal and parallel one above the other, the lower disks B being arranged in the vat A and having their shaft Ct journaled in suitable boxes or bearings in opposite sides of the vat, and the upper disks having their shaft journaled in bearings secured to the posts P P, rising from the aforesaid sides of the vat. To one of said shafts is attached a driviug-pulley O, and, if desired to relieve the chains or bands hereinafter described from the strain of transmitting motion from one of the aforesaid pairs of disks to the other, gears c 0 maybe attached to the shafts of the disks and an intermediate gear a" pivoted to the post P, to transmit motion from the gear 0 to the gear 0, and thus rotate the two pairs of disks in one and the same direction.

Around the two pairs of disks B B are extended two endless bands or chains a a, to

.each of which are firmly secured a series of frames 1) b 1), preferably at the'centers of the lengths of the latter and at right angles to the central portions of the links of the chain, said frames being sustained at such angles by means of braces b 1), extending from the ends of the frames obliquely to the ends of the links and firmly attached thereto. On the inner and outer ends of the frames 1) b are mounted the arm-supporting bars d cl, which are detachably connected thereto in any suitable manner, which may consist in providing the frame with notches or recesses e e for the reception of the ends of the bars d d, and placing across the said notches or recesses straps ll, pivoted at one end and held at the opposite end by removable pins or screws.

"I preferably attach to one or both ends of one of the bars cl of each set or pair pins f f, projecting radially therefrom, and to the post or posts P P, I attach a detent h, with which the said pins come successively in contact during the travel of the bands or chains 0 a, and by said contact the yarn-supporting bars cl 01 receive an intermittent rotation, and thus shift the skeins of yarn longitudinally, said shifting being desired in order to dye the yarn more evenly.

I do not limit myself to the employment of both pairs of disks B B, inasmuch as the lower disks B may be dispensed with and the chains may be made sufficiently heavy to exerta tension on the vertical portions of the chains to prevent the same from kinking, and in this case the driving pulley or gear will be attached to the shaft of the upper disks.

\Vhat I claim as new is 1. A yarn-dyein g machine comprising a dyeliqnor vat, a pair of rotary disks above said vat, endless bands or chains extending around the top portion of said disks and suspended therefrom and passing through the interior of the vat, and yarn-supporting bars carried on said bands or chains to the inner and outer sides of the latter, as set forth.

2. A yarn-dyeing machine composed of a dye-liquor vat, a pair of rotary disks secured to the ends of a shaft arranged axially horizontally in the vat, a pair of rotary disks secured to the ends of a shaft arranged above the vat and axially parallel with the lower shaft, endless bands or chains extending around the two pairs of disks, and yarn-supporting bars carried on said bands or chains at the inner and outer sides of the latter, as set forth. 4

3. A yarn-dyeing machine consisting of a dye-liquor vat, two pairs of rotary disks secured to the ends of shafts arranged axially parallel one above the other, and the lower of said disks dipping in the vat, endless bands or chains extending around the two pairs of disks, frames secured at the center of their lengths and at right angles to said bands or chains, and yarn-supporting bars connected to the inner and outer ends ofthe frames and, parallel with the aforesaid shafts, substantially as described.

4. In combination with the dye-liquor vat A, two pairs of disks BB and chains a a, the frames 1) 12, secured central of their lengths to the centers of the chain-links, the braces 19 1), extending from the ends of the frames to the ends of the links, and the yarn-supporting bars d d, carried on said frames, substantially as described and shown.

5. In combination with the vat A and two pairs of disks B B, the endless chains a a,

frames 1) I), attached to said chains, the rotary yarn-supporting bars d (1, carried on said frames, pins projecting from the said bars, anda detent in the path of the pins,substantially as described and shown.

In testimony whereof I have hereunto signed my name this 20th day of March, 1889.
